ROBERT M. OROSSLAND, OF WASHINGTON, PENNSYLVANIA.

GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 623,237, dated April 18, 1899.

Application filed October 26, 1897. Serial No. 656,467. (No model.)

To all who/7'2, it ntay concern:

Be it known that I, ROBERT M. (JRossLAND, a citizen of the United States, residing at \Vashington, in the county of \Vashington and State of l. enns vlvania, have invented certain new and useful Improvements in Gas- 3urners,of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to gas burners, and particularly to burners employed in cooking and heating stoves using gas as fuel.

The object of my invention is to provide a suitable burner which can be used for heating the lids and oven at the same time or heating either of the same independently of the other, thus producing what might be termed a three-way burner.

Further objects and advantages of the inv vention will appearhereinafter, and the novel features will be pointed out in the claim.

In the drawings, Figure 1 is a plan View of my improved burner. Fig. 2 is a front elevation of the same. Fig. 3 is a central longitudinal sectional view taken on line 1 1 of Fig. 5. Fig. 4 is a bottom plan view showing the air chambers or mixers. Fig. 5 is a horizontal sectional view showing the partitions or walls which form the channels for separating and conveying the gas to the different parts of the burner, the pipe and valve connections being shown in full lines. Fig. 6 is a rear elevation of the burner with the lidburners removed, and Fig. 7 is a transverse sectional view taken on line 2 2 of Fig. 6.

Similar letters of reference indicate corresponding parts in the diiferent figures of the drawings.

A represents the main body of the burner, the interior of which is divided into compartments or channels a, Z), c, and cl by partitions e, f, and g. These compartments or channels are tapped at both ends, as shown at h, for receiving the pipe connections, as also for the purpose of removing the cores from the interior after they are cast. By providing these openings at both ends the device can be fitted up as either a right or left hand burner, whereas otherwise it could only be used as one or the other.

A distributing-chamber B, provided with key-valves, is employed for controlling the gas and is connected with the burner in the mannershown, which consists in screwing a short nipple 2' into the outlets of the valve. On the opposite end of the nipple i is ahalfunionj, which connects with another nipple 7c, which in turn screws into the end of the body of the burner. The holes not used for the connections are plugged.

The distributing-chamber B is open at both ends for receiving the gas-feed pipe, which makes it adapted for right and left hand use. The end not used is plugged. Y

011 the under side of the burner-bod y are two air chambers or -mixers O, which are formed, as shown, with one part longer than the other. The two parts Z and 'm are separated, leaving a space for the circulation of air between them. The shorter part Z has a very fine opening n, through which the gas is expelled. The other part m is provided with a large opening 0, so that when the gas blows out through the opening 12, across the space between the two parts it mixes with the air and is caught up by the opening 0 and conveyed to the channel a, as will be more fully described hereinafter.

On the top of the body of the burner are cast two small turrets p, which form air chambers or mixers. Underneath the turrets are small conical projections q,which are provided with holes 0' for the expulsion of the gas. Screwed into the tops of the turrets are short nipples s, over which are screwed service-e1- bows t, which in turn are screwed into the lid-burners D. These burners D are hollow and are made in two parts, which are held together by screws 10. Holes '1; are formed in the top and sides of these burners, through which the gas escapes. The tops of these burners are also formed with upwardly-projecting teeth 10, which form rests for holding small articles while cooking or boiling.

The rear side of the burner proper is provided with a series of perforations a, through which the gas passes when it is desired to heat the oven.

The operation of myimproved burner is as follows: When it is desired to heat the stove completely that is, the top and oven-all three of the small valves y,g ,and z are opened, thus allowing the gas to pass into the burnerleft-hand burner will be in use.

WVhen it is desired to burn only one of the lid-burners, either the valve 1 or y is opened.

If the valve y is opened,the right-hand burner 1f the valve y is opened, the If it is desired to heat the oven, the valve ,2 will be opened and the gas will pass into the compartment (Z and out through the small opening 02, across the space, and into the air chamber or mixer, where it enters the compartment 60 from the bottom and is expelled through the perforations m, where it is ignited.

The advantage of the burner having two exterior compartments over a single compartment is that it distributes or exhausts the gas or flame more even against the baker-back, thereby giving a uniform heat to the baker, whereas all known burners provided with a single compartment, supply-pipe, and mixerwill be in use.

- openings on the outside force the gas to the farther-most end of the burner-chamber, thereby throwing a strong flame at one end and a very small flame at the opposite end, which gives a very uneven heat to the baker.

Having described my invention, what I claim is An improved triple-way gas-burner,consistin g of a body portion provided with a series of compartments, the inner two of which are provided each with a mixer and a lid-burner thereabove, a compartment on each side of said inner compartments, one of which has a gas-supply, and a discharge-jet on the lower side thereof, the other compartment being provided with burner-openings, and a mixer in alinement with the discharge-jet of the first-named exterior compartment, together with a distributing-chainber provided with valves for controlling and feeding the gas to the different compartments or burners, substantially as shown and for the purposes described.
